In January of this year I started working as a colourist alongside my husband Tom, on the John Matthews graphic novel interpretation of Le Morte D’Arthur. This is an intensely collaborative project – a dead author and a living one, Tom doing all the lines and then me doing the colour, and then Tom doing the final things in photoshop – not least sometimes dropping his lines back in on top of my work. Someone else will be lettering the pages.

I’ve worked collaboratively before, but usually as an author – either writing with other authors (Professor Elemental, Letters Between Gentlemen) or as Tom’s author. There are all kinds of issues around art/words collaborations, but the artist does the art and the author does the words and for your bit you remain yourself, albeit in service to something that is more than you.
